DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0030] Example

[0031] Reference Figure 1 、 4 As shown in FIG. 7 , in one embodiment of the present invention, a polarizer transport box inter-station transfer trolley is disclosed, comprising:

[0032] The bracket body 1 is made of metal and has three vertical layers for supporting and accommodating three transport boxes 5 respectively. A guide column 15 is provided at each of the four corners of the top of the bracket body 1, and a guide column 15 is provided at each of the four corners of the bottom of the bracket body 1. The guide columns 15 and the guide grooves 11 are arranged one-to-one, and the guide grooves 11 and the guide columns 15 are matched in shape. A sealing plate 19 is fixedly provided horizontally at the bottom of the bracket body 1 and at a position higher than the guide grooves 11. Each layer of the bracket body 1 is provided with a slide rod 18 extending along a first direction Y, and the first direction Y is the width direction of the bracket body 1. The bottom of the bracket body 1 is provided with multiple casters 13 to push the trolley to move;

[0033] A limiter 9 is provided on both sides of each layer of the bracket body 1 along the first direction Y. The limiter 9 is configured to be able to slide along the slide bar 18 and rotate with the slide bar 18 as the rotation axis, such as rotating from a horizontal state to a vertical state and finally fixing the transport box 5 to limit the first direction Y to prevent the transport box 5 from shaking or falling off.

[0034] Reference Figure 1As shown, it also includes a sealing bag 2 and a strap. The sealing bag 2 is at least larger than one of the bracket bodies 1 and is used to be sleeved on the outside of the bracket body 1. The volume of the sealing bag 2 can also be larger than the volume of more than two bracket bodies 1 to seal multiple stacked carts. The strap is used to tie the sealing bag 2 and the edges of the sealing plate 19 so that a sealed space is formed inside the sealing bag 2 to prevent dust, moisture, and oxygen from entering the interior of the cart and causing damage to the polarizer.

[0035] Reference Figure 1 As shown, two forklift positioning holes 12 are provided at the bottom of the sealing plate 19 , and the forklift transports the trolley through the forklift positioning holes 12 , which can effectively prevent the trolley from slipping.

[0036] Reference Figure 1 As shown, a brake 14 is provided at the bottom of the bracket body 1. When the trolley is pushed to the designated workstation, the brake 14 can be raised to ensure that the casters 13 leave the ground to prevent the trolley from moving uncontrolled.

[0037] Reference Figure 2 As shown, the height H from the bottom layer of the bracket body 1 to the ground is H, which is greater than 300 mm and less than 700 mm. Since the fork tines of the elevator have a minimum descent height H, the lowest loading layer height H of the trolley is limited.

[0038] Reference Figure 1 and 3 As shown, the bracket body 1 is set as an entrance 8 on the same side of each layer along the first direction Y. The elevator sends the transport box 5 into the trolley through the entrance 8. An anti-collision buffer pad 3 is provided on the other side of the bracket body 1. The anti-collision buffer pad 3 is preferably made of rubber. Since the inertia of the polarizer transport box 5 is large after being loaded into the trolley, the anti-collision buffer rubber pad can effectively prevent the polarizer transport box 5 from colliding with the bracket body 1, thereby avoiding damage to the bracket body 1 after collision.

[0039] Reference Figure 1 、 8As shown in Figure 9, the bracket body 1 is provided with an anti-fool flap 6 at the entrance 8 of each layer, and the anti-fool flap 6 is outside the bracket body 1 relative to the limiter 9, and the anti-fool flap 6 includes a counterweight portion 61, a baffle 63 connected to the counterweight portion 61, and a flip shaft 62 connected between the counterweight portion 61 and the baffle 63. The flip shaft 62 is rotatably connected to the bracket body 1. The anti-fool flap 6 has two states, horizontal and vertical. The weight of the counterweight portion 61 is greater than the weight of the baffle 63. In the absence of external force, the anti-fool flap 6 will automatically flip over so that the counterweight part 61 is located at the bottom of the baffle 63 and abuts against the bracket body 1 and is limited, and the baffle 63 is in a vertical state, which is used to limit the transport box 5 located in the trolley; under the action of the external thrust of the trolley, such as the horizontal thrust of the transport box 5, the baffle 63 can be flipped to a state where it is in the same horizontal plane as each layer of partitions, so that the transport box 5 can enter the interior of the trolley. The function of the anti-fool flip plate 6 is to prevent the operator from not raising the limiter 9 due to negligence after putting in the polarizer transport box 5, thereby causing the polarizer transport box 5 to fall and damage the polarizer or injure the operator.

[0040] Reference Figure 3 、 5 As shown in FIG6 , the limiting flap 7 is further included. The bracket body 1 is provided with the limiting flap 7 on both sides of each layer along the second direction X. The limiting flap 7 is used to fix the transport box 5 located in the trolley on both sides along the second direction X to prevent the transport box 5 from shaking during movement. Specifically, the limiting flap 7 is rotatably connected to the bracket body 1 through a hinge. A locking tongue 71 is provided on the back of the limiting flap 7. The bracket body 1 is provided with a bayonet 17 corresponding to the locking tongue 71. The bayonet 17 A spring is provided inside. When the limit flap 7 is in a horizontal state, the lock tongue 71 is engaged with the latch pin 17 to fix the limit flap 7. The limit flap 7 is provided with a latch pin 72. The bracket body 1 is provided with a latch pin hole 16 corresponding to the latch pin 72. When the limit flap 7 is in a vertical state, the latch pin 72 that is exactly aligned with the latch pin 72 is inserted into the latch pin hole 16 to fix the vertical state of the limit flap 7. The second direction X is the thickness direction of the bracket body 1.

[0041] Reference Figure 3 As shown, the bracket body 1 is provided with an anti-jump pressure plate 4 on the top of each layer. A small gap is maintained between the anti-jump pressure plate 4 and the upper surface of the polarizer transport box 5, which can effectively prevent the polarizer transport box 5 from vertical displacement and vibration during the transportation of the trolley, thereby avoiding shaking, scattering and damage of the polarizer inside the transport box 5.

[0042] Reference Figure 7As shown, the limiting member 9 includes a limiting rod 94, a first clamp 91 and a second clamp 92 that clamp the limiting rod 94 from both sides, a first adjusting bolt 93 and a second adjusting bolt 95, the first clamp 91 and the second clamp 92 both include an upper clamp 91a / 92a and a lower clamp 91b / 92b that are connected, wherein the lower clamp 91b / 92b of the first clamp 91 and the second clamp 92 clamp the sliding rod 18, the upper clamp 91a / 92a of the first clamp 91 and the second clamp 92 clamp the limiting rod 94, the first adjusting bolt 93 and the second clamp 95 are connected, and the lower clamp 91b / 92b of the first clamp 91 and the second clamp 92 clamp the sliding rod 18, the upper clamp 91a / 92a of the first clamp 91 and the second clamp 92 clamp the limiting rod 94, the first adjusting bolt 93 and the second The adjusting bolts 95 respectively pass through the screw holes of the upper clamps 91a / 92a of the first clamp 91 and the second clamp 92, and the through holes of the limiting rod 94 to fix the limiting rod 94, the first clamp 91 and the second clamp 92. The first adjusting bolts 93 and the second adjusting bolts 95 are distributed along the length direction of the upper clamp 91a / 92a, so that the two upper clamps 91a / 92a fully clamp the limiting rod 94 from both sides; when it is necessary to slide or flip the limiting member 9, manually rotate the first adjusting bolts 93 and the second adjusting bolts 95 to loosen the first clamp 91 and the second clamp 92.

[0043] The working principle of the inter-station transfer trolley for polarizer transport boxes described in the utility model is:

[0044] After the box 5 is fully loaded, the anti-fouling flap 6 is restored to its vertical position. When the box 5 is fully loaded, the horizontal limit member 9 is manually flipped to a vertical position and slid to abut against both sides of the box 5 and tighten the adjusting bolt 93 to complete the limitation of the box 5 along the first direction Y. Then, the horizontal limit baffle 63 is flipped to a vertical position and the latch 72 is inserted into the latch hole 16 to complete the limitation of the box 5 along the second direction X. If it is necessary to stack the trolleys, the trolley can be lifted by the elevator to the top of another trolley so that the four guide columns 15 are accurately inserted into the four guide grooves 11 respectively to complete the stacking. Finally, the sealed bag 2 is put on the trolley, and the bag opening of the sealed bag 2 is tied to the edge of the sealing plate 19 with a strap, and the trolley is pushed to the corresponding station.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
